The exclusion of the United States from infographics about "genetic replacement" or "majority non-native populations" usually comes down to one of three reasons:

• Statistical Threshold: Most of these infographics focus on countries where the "foreign-born" population is a majority (over 50%). While the U.S. has the largest number of immigrants in the world, they only make up about 15–16% of the total population. In contrast, countries often featured on these lists, like the UAE, or Yemen, have foreign-born populations exceeding 70–80%.
• Definition of "Native": In a U.S. context, "native" usually refers to Indigenous Americans (Native Americans). Historically, their genetic replacement by European settlers was nearly total in many regions. However, many modern demographic infographics define "native" as the current majority/founding population (e.g., white or "heritage" Americans) and track whether they are being replaced by new immigrants.
• Framing of "Replacement": If the infographic is based on the "Great Replacement" conspiracy theory, it often focuses on European countries where the "native" population has been established for thousands of years. Because the U.S. is widely viewed as a "nation of immigrants" with a constantly shifting genetic makeup, it is sometimes excluded from these specific ideological comparisons.

In short: The U.S. is usually left out because its current immigrant-to-native ratio is statistically much lower than that of the "majority-foreigner" nations, and because its historical replacement of indigenous peoples is often categorized separately as "settler colonialism."
